@ hanjo: you use Lightning that's the reason that Smart Template don't work well. Please deactivate Lightning and Smart Template will work well again!
More informations you can find on my AMO Page (see follow).
I have upload a new SmartTemplate (SmartTemplate4) for Thunderbird 4+ (i'ts exactly the same like Smart Template but an active development)!
